High suspicion of scar endometriosis are painful no-dule in the abdominal scar. Wide surgical excision is the treatment of choice.
Endometriosis has been described as the presence of endometrial tissue outside uterine cavity. Scar endometriosis (SE) is a rare disease reported in 0.03-1.08% of women following gynaecologic surgery. In our retrospective observational cohort study we studied anamnesis, symptoms, surgical procedures and outcomes linked to scar endometriosis in our medical experience from 2004 to 2018.
We reviewed the medical records of 46 patients with a histopathological diagnosis of SE. All patients had a history of at least one previous caesarean section (n=46, 100%). Forty-two patients (91,3%) complained gradually growing nodular abdominal mass near or adjacent to caesarean incision scar, while only 4 patients (8,6%) complained aspecific abdominal pain. Ultrasound scan was performed in all patients (n=46, 100%) and mean size of the nodules at US was 26,8 ± 13,8 mm.
All patients underwent surgery. Seven patients (15,2%) needed mesh implantation, while 39 patients (84,8%) underwent local resection with reconstruction of muscle fascia. Mean follow-up was 31,6 ± 14 months and no patients reported local recurrence of disease.
